What element is gamma?
Gamma Ray. The gamma ray signal detected in wireline logs is derived primarily from the naturally occurring radioactive elements uranium, potassium-40, and thorium. It has been long known that source rocks are often “hot” zones on gamma ray logs.
What is the nuclear charge of gamma rays?
+2e

What is this symbol γ?
Gamma /ˈɡæmə/ (uppercase Γ, lowercase γ; Greek: γάμμα gámma) is the third letter of the Greek alphabet. In the system of Greek numerals it has a value of 3. In Ancient Greek, the letter gamma represented a voiced velar stop /ɡ/.
What is the atomic number of gamma?

| Charge | +2 | 0 |
| Speed | slow | very fast (speed of light) |
| Ionising ability | high | 0 |
What are gamma rays named for?
The name “gamma rays” came from Ernest Rutherford. Ernest Rutherford named the radiation for the first three letters of the Greek alphabet. Alpha rays bounce right off, beta rays went a little farther, and gamma rays went the farthest.
What are the symbols of Alpha Beta and gamma?

Which Ray is dangerous, alpha or gamma?
Alpha particles are the least penetrating and gamma rays are the most penetrating. outside the body beta particles and gamma rays are more harmful than alpha particles as the can penetrate into the body.
What’s an example of a gamma ray?
Example of Gamma Rays Gamma rays are extremely powerful, high intensity electromagnetic radiation, produced by subatomic annihilation. Gamma ray bursts have been observed from explosions in other galaxies. These massive bursts of energy are a major subject of study in astronomy, representing extraordinary levels of radiation.
What is the symbol and charge of a gamma ray?
A gamma ray is photon of light that has the symbol 00γ. Since light does not have mass or charge, we use two zeroes in the symbol. Gamma rays usually are emitted along with other particles. They do not usually appear in nuclear equations since they do not affect the numbers.
Why is gamma radiation dangerous?
Gamma rays or gamma radiation is dangerous because it is ionizing radiation. That is, it is powerful enough to knock electrons from atoms to create ions. In a cell in your body, for example, those ions disrupt the cell metabolism which in turn may cause a number of things to happen.
